Just in case I may need it in the future

Curiosity has me... jig for mounts?

[Gomez]

Yes. Since they are a pain in the butt to make while the engine is in the bay, why not...... lol

I plan on making one for the Pass side too. Then eventually one for the crossmember, since there are 4 known different crossmembers.

[frogman]

Out of curiosity, what are the 4 types? I would guess: 4 spd MTX, 5 spd MTX and I'm out of guess's.

Nice looking jig!

[Gomez]

That would be an F3BZ question. There was a post a while back where it showed different part numbers. In conversation with shadetree at my house this past summer We agreed there is something about the cross-members that a finger just can't be put on. Like, without swapping cross-members you have a good chance of mounts not fitting from car to car kind of thing.

From the motor mount thread

So according to my interchange guide there are four different crossmembers out there. Wonder if this is part of some of the fitment issues Im having.

4 and 5 spd are identical and use the same mounts.
tranny housing is identical between 4 and 5 spds, only difference is internal.

i didn't know there were 4 styles till reading this post. anybody ever do a comparison between early/late supports? i don't think it would be the support to body mounting points. maybe its a difference in the trans mounting pads? part#s 90-93 ATX - F0BZ6A023B. MTX - F0BZ6A023A. 88-89 ATX - E9BZ6A023A. MTX - E9BZ6A023B.

I have all 4 they're all in use though so I haven't compared them

Take them all out at once and take a comparison photo. We expect pics and measurements first thing in the morning. lol

According to rock auto the rear trans mount is the same 88-93 MTX; and of course the axles and transmission cases are the same, so if there is a difference then I'm thinking it isn't related to the mounts.
ATX is another story.

Awsome! So how much for a set.of mounts!

Awsome! So how much for a set.of mounts!

They put the engine 2 inches forward and 1 inch lower as compared to a stock 93 B3 with Auto tranny. I also moved the combo towards the drivers side about 1/8 inch past the frame horn so I had to notch it. I also added a plate to the top of the crossmember so I could use the stock auto front rubber mount with a modified XR2 front bracket. It is placed on top of the member. The rear mount, (both pieces) also from an XR2, is modified in every respect to use the stock location on the crossmember. The pass mount utilizes the original B3 engine bracket and rubber mount but the rest is completely custom. I hope to get them powder-coated very soon so I will take some good pics of the final product. I guess if someone is willing I may be willing to sell up a complete set. I am sure with your fab skills you are just putting out a nice compliment. Thanks,

Meh I've got to get my megasquirt sorted out right now... I'm suffering from boost withdrawal. Lol
