So learning the hard way to not cut corners I bought a used bellhousing for $100 that is at the link here:
http://www.summitracing.com/parts/lak-15003/overview/
Doing a search for my 73 nova has brought up this bell housing:
http://www.summitracing.com/parts/lak-15000
They seem to have the same measurements from what I can tell, but my trans won't bolt up it has the right pattern but I'm like 1/2 inch away from connecting. I've aligned the clutch with the plastic tool, I've aligned it with the trans input shaft, I've even put the trans into the bell with the clutch on the threads held the clutch down and tried to get it down further. I thought it wasn't going into the pilot bearing but now I'm guessing it's the bell housing possibly, I'm open to any suggestions or ideas, thanks fellas. Btw the engine is a 283 from a 66 impala transmission is a BW super T10 with 2 grooves going into a 73 nova

Over 40 views and people have the same amount of knowledge as me? Guess I will be calling summit and seeing if they can give me an answer, I will post back if I get an answer since nobody knows

15003 has mounting holes in the bell for tri-five cars and the 15000 does not?

15003 has a z-bar bracket the other does not. I would go to Lakewoods web site, they would have all the details

So as far as you guys can see they have the same measurements? This swap is becoming a hassle because of this last 1/2inch

So here is my guess. If the trans won't bolt up you probably did not dial in the bellhousing using a dial indicator. This is a very critical step, especially when installing a manual trans with any Lakewood product. I had the same issue, even the same 1/2" when I installed my Muncie 4-speed with a new Lakewood Bell. After I dialed it in the trans slipped right in. The Bell hole must be perfectly centered with the center of the pilot bearing. You may need to install new pins http://api.viglink.com/api/click?format=go&jsonp=vglnk_14125224043158&key=fc393c85c345c384b12d5989e3c26047&libId=0077b2bd-f511-479b-9b8f-b99fdd1928e5&loc=http://www.novas.net/forums/showthread.php?t=17664&v=1&out=http://www.jegs.com/i/Lakewood/620/15907/10002/-1&ref=http://www.novas.net/forums/search.php?searchid=1632586&title=Bellhousing Dowell Pins - Nova Tech&txt=Lakewood 15907 to get it aligned properly. Sorry for the late reply. Jack

Thank you for this reply, I was going to do that and when I went to buy a digital caliper my dad said "oh your don't need one of those, you just bolt everything up" I'm assuming when he use to work on manual cars they weren't conversions so that part wouldn't be necessary so I'm gonna take the bell off and do this properly and see what I come back with, thanks for the replies everyone

Sometimes those plastic clutch align tool doesn't always align perfectly.
As I'm tightening down pressure plate i feel around the edge of disc and plate to make sure they are even.

Follow the advice Jackel gave you. You can search TREMEC Installation to see how to align the bellhousing to the pilot bearing.

That last 1/2" is usually the pilot shaft not going in the pilot bushing/bearing unless you can see the bearing retainer on the front of the trans is butting up to the bellhousing hole but not fitting in then that's the issue.Even with some disc misalignment,if you had a buddy push the clutch pedal to the floor (assuming it's adjusted to completely release the disc) while you horse the trans but still couldn't get it to slide in I would check the pilot bushing/bearing.I prefer a bushing over a bearing because if a bearing piles up during use it will trash the input shaft of the trans,an oilite bushing normally will not.The problem with the bushing is it's so soft that on install it's easy to squish the hole and make it too small.The clutch alignment tool may go in but the trans may not.I would first verify the trans input will actually slide into the back of the crank.Zeroing the bell is also good practice,a necessity if using a pilot bearing,and will ensure a smooth shifting trans.

If you are using a Lakewood BH you definitely need to dial it in. They are stronger, but not as precisely built as a stock cast piece. RobMCPerformance has nice offset dowels, reasonably priced, and great directions on their website. Super easy to deal with and these dowels lock down once you dial them in. You'll also need a good dial indicator. I just did this on my car and it's straight forward. My Lakewood bellhousing center hole was not perfectly round, so watch out for that. It can throw you off. Once the housing is located correctly, the trans just slides right in. Dean

When you have the bellhousing off make sure it fits to the front of the trans that the center hole in the bellhousing isn't too small for the bearing retainer that's bolted to the front of the trans. I've heard that the older style muncy's had a smaller diameter bearing retainer sounds like you're bellhousing is or an older Chevy... Just a thought good luck.(y)
