Does anyone have the dimentions for motor mount adaptor plates? There was 2 pics in one of the FAQ's but both links were no good. Im going to make a set and a print would be gratefull. Also any first gen camaro guys here have the dimentions for the 4 sfront sub frame mounts, im goin to spin up a set of aluminum ones once i get the dimentions. Need to change them while I do the ls1 swap.
Strange that print shows the holes at 9/16", seems way big to me. Bolts are either 10mm or 3/8", both of which are smaller than 7/16". Also, wondering where these mounts will place the bell housing flange in relation to a traditional small block? Also, just noticed it calls for the third hole from the left, at the top, to be countersunk for a flat head bolt, pretty sure it needs to be the second from the left, as that one will be underneath the motor mount.
HTH, Jim

I took a LS MM and traced it out, then measured 1" forward (engine set-back) and used a SBC 3 bolt MM and traced it out.
Then I just bought a pair off Ebay for $40 but they came PC'd and with bolts.
yeah, that design is wrong. I addressed it in the "LS1 Swap FAQs" thread. You can see where the countersink should be in S&P's instructions (second photo down).
LS1 Motor mount plates, prints?
